Bryan Silverman here. I just wanted to say thank you for all of your interest and address what you have been saying with the ink. The ink is soybean based and it does not run on your body or in the water when it is used. If you were to close your eyes, you would not even know there is ink there! Also, the ink is only printed on the toop ply of the toilet paper so you could always use the back if you would want to.
